PERMANENT WAY FOR RAILWAYS.

SPECIFICATION forming part of Letters Patent No. 230,816, dated August 3, 1880.

Application filed J nne 5, 1.880.

To all whom it may concern Be it known that I, WILLIAM RAINBOW, of

Chancery Lane, in the county of Middlcsex,

England, have invented a new and useful Improvement in Permanent \Vays of Railways and I do hereby declare that the following is a full, clear, and exact description of the same, reference being bad to the accompanying drawings, forming part of this specification.

My invention is an improvement in that class of railways in which no wooden ties are used, and the pot-sleepers or chairs are flared to rest directly upon the ground, and are cast in one and the same piece with a jaw which is perforated with holes for the fish-bolts, between which jaw and the fish-plate the rails are bolted.

My improvement consists, mainly, in the means for connecting these chairs so as to preserve the gage of the road, as hereinafter more fully described.

In the drawings, Figure l is a transverse section through one of the pot-sleepers. Fig. 2 is a plan of the same. Fig. 3 is a plan of a 'modification, and Figs. 4 and 5 a section and a plan of a further modification.

A is an ordinary cast-iron pot-sleeper, and B is a jaw or half-chair cast upon the top table of the sleeper, and ofa form to correspond to the profile of the rail, as shown. This jaw B answers both the purpose of a chair and of a fish-plate for fish-jointing the ends of the rails.

t is of the same length as an ordinary fishplate, and is cast with recesses on the back of it and holes through it for the heads and shanks of the fish-bolts O, which pass through the same, through the web of the rails, and through an ordinary fish-plate, D, on the opposite side, and are secured by nuts. as usual.

The holes in both B and D are slightly oblong to allow for expansion and contraction of the rails, and the square heads of the bolts fit loosely in the recesses for the same purpose, but yet so as to prevent the bolts turning when tightened up.

In Fig. 3 B is an intermediate chair. It is shorter and has no bolts through it, but is otherwise similar to Figs. 1 and 2.

E is a cross-tie to maintain the gage of the (No model.) Patented in India November 23, 1877.

line. This cross-tie is of peculiar construction, and serves not only the purpose of a cross-tie, but also that of a clip, which, in combination with the jaw B at the opposite side of the rail, serves to hold the rail securely down upon the pot-sleeper. For this purpose it is cranked at e, and provided at 6 with a lug or projection which rises above and fits upon the foot of the rail, as shown, and holds the same firmly down upon the sleeper. This cranked part of the cross-tie passes through a transverse slot made partly in the top table and partly in the sides of the pot-sleeper A, and its straight extremity passes close under the top table of the sleeper, and is secured at the opposite side by a key, E. The sleeper A is strengthened at this part by two transverse parallel ribs, to, on the under side, between which the cross-tie passes. The cross-tie is thus immovably attached to the sleeper on the one side by the key E and on the other by the lug or clip 0, so as to maintain the gage of the line accurate, and at same time, in combination with jaw B, clamp the rail securely to the sleeper. The latter purpose is served more particularly at the intermediate chairs, Fig. 3, where the rail is not otherwise secured.

To enable the one rail to be removed withoutloosening the other from its chair, the cross-tie E is in two parts, united at the middle of the track by a joint, 11, consisting of a wrought-iron clip, h, embracing the overlapping ends of the two parts of the cross-tie, so as to make a rigid joint with a bolt, 1', passing through the whole and secured by a nut, as shown.

In Figs. 4 and 5 an ordinary straight cross tie is used, which passes directly across beneath the table of the sleeper through slots in the sides, and is secured at either side by keys E.

WVhat I claim as new is- 1. The combination, with the cross-tie E, adapted to pass beneath the rail, of the sleeper A, with jaw B, having a slot beneath the jaw flanked on opposite sides by the ribs a a, as and for the purpose described.
